Hello Aaron,
Don't mix up x and theta !
If you want to use NIntegrate, just use Evaluate :
In[9]:=
Integrate[x*Sin[x]*{1, 2}, {x, -Pi, Pi}]
Out[9]=
{2*Pi, 4*Pi}
In[12]:=
NIntegrate[Evaluate[x*Sin[x]*{1,2}],{x,-Pi,Pi}]
Out[12]=
{6.28319,12.5664}

Objet : [mg52940] NIntegrate a list
Hi,
I can Integrate this, but apparently not NIntegrate this:
Integrate[x*Sin[x]*{1, 2}, {theta, -Pi, Pi}]
but not
NIntegrate[x*Sin[x]*{1, 2}, {theta, -Pi, Pi}]
Is there a good way to do this (w/o writing loops)?
Many thanks!
